Thermal cutoffs are compact one shot safety devices that disconnect electrical circuits when the operating temperature exceeds a preset trip point. They provide reliable overheat protection for heating elements and power electronics. Designed to be installed in series with the load, once activated they cannot reset and require replacement. Benefits - Protect against overheating and fire risk by interrupting current at the trip temperature - Easy to install with pre attached leads and variable lead lengths - Consistent known trip temperatures enable precise safety design - Small cylindrical form factor fits in tight spaces without modifying equipment Key attributes - Trip temperature fixed rating available to match appliance safety requirements - Form factor cylindrical metal housing with insulated leads - Materials metal body, ceramic core, heat resistant insulation - Performance fast response at the target temperature; reliable operation in typical service conditions Compatibility - Suitable for appliances with heating elements such as hair dryers, irons, toasters, and coffee makers - Used in power supplies, soldering irons, and other hot components - Applicable to heaters, motors, and battery packs where thermal protection is needed Use scenarios - In a hair dryer, the cutoff sits in series with the heating element to cut power if airflow is blocked or element overheats - In a coffee maker, the cutoff protects the heating plate from overheating if the thermostat jams - In a 3D printer power supply, the cutoff provides a safety shutoff if the nozzle or bed overheats
